| minimum en route altitude |
The altitude above sea level (ASL) between specified fixes on airways or air routes that assures acceptable navigational signal coverage and that meets the IFR obstacle clearance requirements |
|
| minimum en route IFR altitude |
The altitude above sea level (ASL) between specified fixes on airways or air routes that assures acceptable navigational signal coverage and that meets the IFR obstacle clearance requirements |
|
| minimum equipment list |
A document approved by the Minister pursuant to CAR 605.073 that authorizes an operator to operate an aircraft with aircraft equipment that is inoperative under the conditions specified therein and that may specify certain equipment that must be operative. |
|
| minimum fuel |
An expression used to inform ATC that an aircraft’s fuel supply has reached a state that is sufficient to reach destination, provided that unexpected delays are not encountered |
|
| minimum holding altitude |
The lowest altitude prescribed fora holding pattern that assures navigational signal coverage, communications, and meets obstacle clearance requirements |
|
| minimum IFR altitude |
The lowest IFR altitude established for use in a specific airspace. Depending on the airspace concerned, the minimum IFR altitude may be a minimum obstacle clearance altitude (MOCA) a minimum en route altitude (MEA) a minimum sector altitude (MSA) a minimum vectoring altitude (MVA) a safe altitude 100 NM, an area minimum altitude (AMA) a transition altitude or a missed approach altitude. The minimum IFR altitude provides obstacle clearance but may or may not be within controlled airspace. |
|
| minimum navigation performance specifications |
An expression used to designate specifications relating to the navigation performance capability of aircraft operating in specified portions of the airspace |
|
| minimum obstacle clearance altitude |
The altitude above sea level (ASL) between specified fixes on airways or air routes that meets the IFR obstacle clearance requirements for the route segment in question |
|
| minimum reception altitude |
When applied to a specific VHF/UHF intersection, the lowest altitude above sea level (ASL) at which acceptable navigational signal coverage is received to determine the intersection |
|
| minimum safe altitude |
An altitude depicted on approach charts that provides at least 1000 ft of obstacle clearance for use within a specified distance from the navigation facility upon which a procedure is predicated |
|
| Minimum Safe Altitude as defined in the FLIP General Planning Document |
MSA |
|
| minimum safe altitude warning |
A function of certain ATC automated systems that is designed to alert radar controllers to existing or pending penetrations of a minimum safe altitude that is recognized by program parameters and requires immediate attention or action |
|
| minimum safe speed |
The minimum speed at which an aircraft may be operated without affecting its manoeuvring ability. This speed may vary depending on the aircraft type and configuration, or emergency conditions. |
|
| minimum sector altitude |
The lowest altitude that will provide a minimum clearance of 1000 ft under conditions of standard temperature and pressure above all objects located in an area contained within a sector of a circle with a 25 NM radius centred on a radio aid to navigation or a specified point |
|
| minimum vectoring altitude |
The lowest altitude for vectoring aircraft by ATC that meets obstacle clearance and radio coverage requirements in the airspace specified |
|
| missed approach |
That part of an instrument approach procedure (IAP) between the missed approach point (MAP) the missed approach waypoint (MAWP) or the point of arrival at decision height (DH) and the specified missed approach NAVAID, intersection, fix or waypoint, as appropriate, at the minimum IFR altitude. It is in this part of the approach procedure that the aircraft climbs and returns to the en route structure or is positioned for holding or a subsequent approach. The route of flight and altitudes are depicted on instrument approach charts. |
|
| missed approach holding waypoint |
The waypoint designated in the missed approach segment of an instrument approach procedure (IAP) to which the aircraft will automatically fly and, upon reaching the geographic position of the waypoint, enter a specified holding pattern |
|
| missed approach point |
The point on the final approach course that signifies the termination of the final approach and the commencement of the missed approach segment. It may be (a) the intersection of an electronic glide path (GP) with a decision height (DH) a NAVAID located on the aerodrome; (c) a suitable fix (e.g. distance measuring equipment (DME)) or (d) a specified distance beyond the NAVAID or final approach fix (FAF) not to exceed the distance from that NAVAID or fix to the nearest boundary of the aerodrome. • U.S.: abbreviation: MAP • ICAO: abbreviation: MAPt or MAPT |
|
| missed approach procedure |
The procedure that is to be followed after an instrument approach procedure (IAP) if, for any reason, a landing is not effected and that occurs normally (a) when the aircraft has descended to the decision height (DH) or has descended to the minimum descent altitude (MDA) and reached the missed approach point or waypoint, and has not established the required visual reference to land; or (b) when the aircraft is directed by ATC to pull up or to go around |
|
| missed approach segment |
That part of an instrument approach procedure (IAP) between the missed approach point (MAP) the missed approach waypoint (MAWP) or the point of arrival at decision height (DH) and the specified missed approach NAVAID, intersection, fix or waypoint, as appropriate, at the minimum IFR altitude. It is in this part of the approach procedure that the aircraft climbs and returns to the en route structure or is positioned for holding or a subsequent approach. The route of flight and altitudes are depicted on instrument approach charts. |
